About Our Manufacturing Process

Raw material preparing
Eco Friendly Plastic Bags

Rapidly growing concerns related to environmental and health safety, restricting use in petrochemical raw materials, reducing carbon footprint...are among the few factors driving inclination towards use of biopolymers. With our professional R&D center and strong manufacturing capabilities, Torise Biomaterials can produce 200,000 tons of biodegradable modified resins annually.

Compostable Raw Materials

How is it made

PLA (polylactic acid) is typically made from the sugars in corn starch, cassava or sugarcane. It is biodegradable, carbon-neutral and edible. To transform corn into plastic, corn kernels are immersed in sulfur dioxide and hot water, where its components break down into starch, protein, and fiber.

The kernels are then ground and the corn oil is separated from the starch. The starch is comprised of long chains of carbon molecules, similar to the carbon chains in plastic from fossil fuels.

Some citric acids are mixed in to form a long-chain polymer (a large molecule consisting of repeating smaller units) that is the building block for plastic.PLA can look and behave like polyethylene (used in plastic films, packing and bottles), polystyrene (Styrofoam and plastic cutlery) or polypropylene (packaging, auto parts, textiles).

Manufacturing Process

With strong production capabilities, we can produce 300,000 tons of sustainable products each year. Our production capabilities are not only reflected in our production lines, but also in our flexibility and response speed. Whether it is mass production or small batch customization, we can quickly adjust the production plan to ensure on-time delivery.

Raw materials feeding

We insist on developing and applying a serious of fully degradable and modified resins such as PLA, PBAT which is a new type of bio-based and renewable biodegradable material made from starch raw materials. It can be completely decomposed by microorganisms in nature under specific conditions, and it will generate carbon dioxide and water without polluting the environment.

Extrusion and Printing

Plastic pellets are melted in an extruder and then extruded through a die to form a film. The film is then cooled, stretched, and treated to give it strength and flexibility. As needed, printing and coating are performed on the surface of the film. Typically, flexographic printing is used to print the desired design onto the film surface.

After the film is printed and coated, it can be cut into various shapes and sizes according to the requirements of the product. This cutting process can be performed using a variety of methods, such as slitting, rewinding, or die cutting, depending on the specific needs of the product.
